(Summary description)The layout of the power-off brake motor is simple: the parts are small, the reliability is high, the air gap adjustment is easy, and the maintenance is convenient. Small size, light weight, easy to install, the motor and the brake are connected as a whole, the volume is reduced to a very small, the weight is also light, the layout is firm, and the small space can be installed. The brake noise is low, and the DC brake is adopted, without electromagnetic noise, and the brake noise is low.

The brake motor has high-precision positioning requirements. As a brake motor, it should have the following characteristics: fast braking, accurate positioning, reliable, interchangeable application of the brake system, simple layout, easy replacement and maintenance, etc. Many manufacturers need brake motors to control the inertia of the motor and reach the required accurate positioning to realize the automatic operation of the machine.
The layout principle of the brake motor, the power is cut off, the brake armature is released and the spring resets the armature to compress the conflict disk, the motor shaft is held by the conflict disk, and the brake maintains the load. The brakes will wear out during the application process. Good brake pads are wear-resistant and the braking force is maintained. However, the environment of brake wear should be checked under long-time and frequent application to avoid brake failure and ineffectiveness. The inspection technique is to open the air hood of the motor, adjust the brake clearance, the clearance is 0.4-0.7 mm, if the wear is tight, it is recommended to replace the brake assembly.
There is an electromagnetic holding brake at the rear of the brake motor. When the motor is energized, it is also energized to pull in. At this time, it does not brake the motor. When the motor is powered off, it is also powered off. The holding brake brakes the motor with the benefit of the spring. Rotor open circuit voltage measurement When measuring the rotor open circuit voltage, the rotor is stable, the rotor winding is open, the starting varistor is disconnected, the rated voltage is applied to the stator winding, and the voltage between the lines is measured between the rotor collector rings. The rated voltage is above 500V The variable speed delay motor, the voltage applied to the stator winding can be properly reduced.
